Boost Logic Formula Series Quadzilla Titanium Midpipe for R35 Nissan GT-R

Boost Logic’s Quadzilla Titanium Midpipe for R35 Nissan GT-R is a Formula Series midpipe that splits the twin 75mm inlets into four 60mm tubes before merging them into a single 90mm outlet, a layout Boost Logic tuned for a throatier tone low in the rev range and a higher pitch near the top. It is fabricated entirely from titanium, TIG welded, and weighs 3.8 lbs per Boost Logic. It bolts to the stock downpipes and muffler-back exhaust or most aftermarket systems, so it works on a stock daily driver and on a high-horsepower build alike; it is a sound upgrade first, and Boost Logic publishes no dyno figure for it.

Design and Performance

  • Boost Logic developed its first GT-R midpipe shortly after the car launched and revised it several times before the Quadzilla. The quad tube center section is meant to give the tone of a resonated unit without its restriction, and a proper merge collector feeds the single 90mm outlet for high flow with no drone, according to Boost Logic.

Features

  • 100% titanium construction, precision TIG welded
  • 2 x 75mm inlet tubes into 4 x 60mm tubes into a single 90mm outlet
  • Four large 2 3/8-inch primary section pipes for unrestricted flow
  • Merge collector designed for high flow without drone
  • Lightweight at 3.8 lbs as rated by Boost Logic
  • Quad tube design tuned for a deeper low-rev tone and a higher pitch at high rpm

Applications

  • Nissan GT-R: R35 | 2009-2024 | 3.8L VR38DETT V6

Notes

Frequently Asked Questions

  • Does the Boost Logic Quadzilla Titanium Midpipe for R35 work with the stock exhaust? Yes. Boost Logic designed the Quadzilla Titanium Midpipe for R35 to bolt to the stock downpipes and the stock muffler-back exhaust, and it also fits most aftermarket systems. All gaskets and hardware are included, so a stock GT-R can take the midpipe on its own and keep the rest of the factory exhaust in place.
  • How much does the midpipe weigh? Boost Logic lists the Quadzilla at 3.8 lbs, built entirely from titanium. Titanium keeps its rigidity at very high exhaust temperatures, which is why Boost Logic chose it over steel for this part, and the low weight takes mass out of the car compared to the factory system it replaces.
  • How does the Quadzilla change the sound? Boost Logic tuned the quad tube layout for a throatier, resonated tone low in the rev range and a higher pitched note at high rpm than the VR38 normally makes. The merge collector is designed to avoid drone, and Boost Logic describes the result as the refined sound of a resonated unit without the flow restriction.
  • Does it add horsepower? Boost Logic says the midpipe increases horsepower, efficiency and response, but it does not publish a dyno figure or the setup it was measured on, so no specific gain is claimed here. The unrestricted design is intended to support later engine and turbo upgrades without the midpipe becoming the limit.
  • Which GT-R models does it fit? It fits the 2009 and later Nissan R35 GT-R, and Boost Logic lists USDM, European and JDM models. Fitment follows the factory downpipe and muffler-back connection points, so cars with custom downpipes or a one-off exhaust should confirm compatibility with Bulletproof Automotive before ordering.
